The last A380 will be produced in 2021, a reflection of how twin jets dominate the market for the largest airliners.

Passenger popularity is why some operators will operate A380s well into the future, as reflected by Singapore Airlines recently introducing a revised premium cabin pictured here.

Airbus has ruled out stretching the A350-1000 to create a higher-capacity A350-2000 variant in the short term.

Airbus has only sold 180 A350-1000s, now its highest-capacity airliner.

Qatar Airways was the first airline to put the A350-1000 into service in February 2018.

AirBridgeCargo Boeing 747-8F VQ-BLR (c/n 37068) is one of seven 747-8 Freighters operated by the airline.

Lufthansa is one of only three airlines to operate the 747-8 Intercontinental, the passenger version of the 747-8, the others being Air China and Korean Air Lines. Here D-ABYA (c/n 37827) is pictured in Hamburg.

Only 51 examples of the Boeing 747-8 Intercontinental have been sold. This one, N6067U, later N828BA (c/n 37826), is pictured back in 2013 test flying a performance improvement package. This aircraft is now stored.

At 251ft 9in (76.72m) in length, the Boeing 777X is the longest twin-jet airliner ever developed. Here the first test aircraft, N779XW (c/n 64240), is pictured taxiing at Everett in June 2019.

The 777X will feature a folding wingtip mechanism to ensure airport gate compatibility and efficient performance in flight.

The GE Aviation GE9X turbofans with their 134in (3.4m) fan diameter are the largest engines ever developed for a commercial aircraft, and their size is apparent in this shot of the first Boeing 777-9 undertaking its first taxi and brake tests at Everett in June 2019.
